[QUOTE="pcrepair, post: 262, member: 1"] The display issues you're experiencing with your old Dell Optiplex are likely due to the Radeon HD5450 graphics card. Here are a few steps to diagnose and potentially repair the issue: [HEADING=2]Steps to Diagnose the Issue[/HEADING] [LIST=1] [*][B]Check Connections[/B]: Ensure the graphics card is properly seated in the PCIe slot and that all connections are secure. [*][B]Test Integrated Graphics[/B]: [LIST] [*]Remove the Radeon HD5450 and connect your monitor to the onboard graphics. [*]Power on the system and check if the display issue persists. If the display is clear, the problem is likely with the Radeon HD5450. [/LIST] [*][B]Inspect the Graphics Card[/B]: [LIST] [*]Remove the graphics card and visually inspect it for any physical damage, such as blown capacitors or burnt components. [*]Clean the card and its connectors with compressed air to remove any dust that might be causing poor connections. [/LIST] [/LIST] [HEADING=2]Potential Repairs[/HEADING] [LIST=1] [*][B]Reapply Thermal Paste[/B]: Over time, the thermal paste on the GPU can dry out, leading to overheating issues. Reapplying fresh thermal paste can sometimes help. [*][B]Reflow Solder Joints[/B]: [LIST] [*]If you suspect the problem is due to poor solder joints, a process called "reflowing" might help. This involves heating the GPU to re-melt the solder. However, this is a delicate process and can be risky without proper equipment. [/LIST] [*][B]Driver Update/Reinstallation[/B]: [LIST] [*]Boot into Safe Mode (if possible) and uninstall the current graphics drivers. [*]Reboot and install the latest drivers for the Radeon HD5450 from the AMD website. [/LIST] [/LIST] [HEADING=2]Further Steps[/HEADING] [LIST] [*]If the above steps don't resolve the issue, the graphics card might be failing, and a replacement could be necessary. Consider testing the Radeon HD5450 in another system if possible to confirm it's the root cause before purchasing a new one. [/LIST] [HEADING=2]Alternative Solutions[/HEADING] [LIST] [*][B]Using Onboard Graphics[/B]: If the onboard graphics are sufficient for your needs, you could use them instead of the external graphics card. [*][B]Budget Replacement[/B]: If you need a replacement, there are budget-friendly graphics cards available that could be a good fit for your system. [/LIST] By following these steps, you should be able to determine if the Radeon HD5450 is the issue and whether it's repairable or needs replacement. [/QUOTE]
